Maitiro ekudzivirira zvishwe muParallel Operation yeJenareta

Parallel Operation zvinoreva kuti maviri kana anopfuura majenareta seti ane yakaenzana rated voltage uye inopindirana nhanho inosanganiswa mubhazi rimwe chete kupa simba rinoshanda uye reactive simba kune mudziyo.Imwe jenareta seti inotanga kutanga, uye ipapo magetsi anogadzirwa anotumirwa kubhazi.Mushure mekunge imwe jenareta seti yatangwa, iri kufambirana neyakapfuura jenareta yakaiswa panguva ino.Panguva yekuvhara, jenareta seti haizove neabnormal impulse ikozvino, uye crankshaft haizokanganiswe kamwe kamwe.Nekudaro, dunhu rose razvino rinofanirwa kutariswa zvakakwana mumatanho ekushanda ekushanda kwakafanana.

1. Reverse basa.Mamiriro ezvinhu aripo e reverse simba anokonzerwa nekumhanya kwakasiyana uye voltage ye jenareta zvikamu , kureva, imwe jenareta unit ine simba rakanaka uye imwe unit ine simba risina kunaka.Mune mamwe mazwi, iyo unit ine simba rakashata inova mutoro panguva ino (mamiriro ezvinhu epanguva ino yekuderera uye kusingaenderani nekukurumidza kwechikwata ichi).Kana iyo voltage isingaenderane, iyo unit ine high voltage inopa imwe reactive ikozvino uye reactive voltage kune iyo unit ine yakaderera voltage (chiratidzo chakanaka cheammita yechikamu ichi).Izvo zvakaenzana nekuwedzera boka re condenser mumagetsi emagetsi.Panguva ino, iyo unit ine low voltage inova mutoro wakakura uye inogamuchira yakakura reactive ikozvino kuti ive nechokwadi chekuyeresa kwevoltage yezvikamu zviviri (ammeter yeiyi unit inoratidza kumashure).Munguva yekutarisa, kana voltage yeimwe unit yakawedzera kana kuti voltage yeimwe yuniti yakawedzera, imwe unit ine reverse simba ikozvino, uye maitiro ayo ikozvino anenge makumi maviri muzana eiyo yakayerwa ikozvino.Reverse acting relay zviito, nzendo uye maaramu, asi haivharike.

2. Overcurrent.Iko kubuda kweiyo seti yejenareta yanhasi inoenderana, uye huwandu hwayo hwekuremerwa hwakaderera kwazvo.Mazhinji acho akatenderedza 5% yehuwandu hwekubuda.Iyo inobvumidzwa yekuremedza nguva ndeye 15 ~ 30 maminetsi, kusvika ku60 maminetsi.Kupfuura nguva ino, the Perkins jenareta seti ichave inopisa, kusungirirwa kwetambo kuchaderedzwa, uye hupenyu hwebasa huchaderedzwa.Nokudaro, kana pasina chinodikanwa chakakosha pakugadzirisa kuchengetedzwa kwepamusoro, kuchengetedzwa kwepamusoro kunogona kuiswa pa 110% yehuwandu hwemazuva ano.Panguva yekuyedzwa kwemutoro, unza iyo ikozvino ku110% yeyakayerwa ikozvino, uye overcurrent relay zviito.Rwendo, alarm uye kusadzima.

3. Overvoltage.Kana iyo jenareta seti inoshandiswa mukufanana, inonyanya kutya iyo oscillation yemagetsi ekupa system.Kana iyo oscillation ichinge yaitika, kukwira kwemagetsi kweiyo sisitimu kuri nyore kuburitsa kuparara kwemidziyo yemagetsi uye magetsi emagetsi system, izvo zvinoita kuti magetsi emagetsi uye zvivakwa zvemagetsi zvisakwanise kushanda zvakajairika.Naizvozvo, maseti ejenareta anoshandiswa mukuenderana ane kuchengetedzwa kweovervoltage, uye kukosha kwayo kwekutanga kwe105% yevoltage yakayerwa iri nani.Short circuit overvoltage relay, rwendo, shutdown uye alarm.Zvinogona kuonekwa kuti kukurumidza (frequency) kugadzirisa kwezvikamu zviviri kunofanira kuwirirana kusati kwagadzirira kushanda kwakafanana kwezvikamu zvejenareta.Mukufanana, kumhanya kwemuchina wekutanga kana boka rinofananidzwa rinogona kugadziridzwa zvinoenderana nekutenderera kwekumhanya kwetafura panguva imwe chete, kuitira kuti kutenderera kwetafura panguva imwe chete kutenderedzwa newachi kana kuchinjika. .Iyo inononoka kumhanya ndeye, zviri nani, asi chinongedzo chetafura munguva imwe chete chinofanira kutenderedzwa isati yave padivi nepadivi.Pakupedzisira, mushure merutivi-ne-kurutivi, tarisa kana ikozvino uye kukwanisa kwezvikamu zviviri zvakaenzana.Kana mutsauko wakakurisa, gadzirisa knob yekumhanyisa kuchengetedza simba.
